It happens with paid subscriptions as well.

Some examples of this, that I can think of:

- Varnish Cache where you need a paid subscription, or community patches and you have to do the compilation yourself, to make it understand SRV-records instead of hardcoding IPs or hostnames.

- Nginx also need a paid subscription to understand SRV-records.

Both of these companies have realized that in order for people to effectively run the software within a cluster, you need support for SRV-records to get service discovery working.
